This application relates to the field of seismic measurement technology, and provides an apparatus and method for measuring cross-fault motion in experimental earthquakes. The apparatus includes a metal rod, an elastic compression spring installed at the first end of the metal rod, and a rod axial force gauge installed on the metal rod. The method involves installing the apparatus on a fault model and calculating fault motion. Based on the tensile stiffness K1 of the apparatus for measuring cross-fault motion in experimental earthquakes and the data recorded by the rod axial force gauge, the axial displacement of the metal rod, the shear displacement in the fault shear direction, and the real-time velocity and acceleration of the fault motion at time t are calculated. The apparatus for measuring cross-fault motion in experimental earthquakes of this application has a simple structure, is easy to manufacture, and can capture vibration information during fault instability without the need for complex field equipment deployment. It is not easily affected by the environment, and the test results are accurate. The method can accurately describe the instability process of experimental earthquakes.
